Application filed January 9, 1922. Serial No; 527,958.

To all 10/10772 it may concern I Be it known. that we, AXEL B. SKEPPSTEDT and ELI HADnoN, citizens of the. United States, residing at Chicago, in the county. of Cook and State of Illinois, have invented new and useful Improvements inYPasting Machines, of which the following is a specification.

The machine which is the subject matter of the present application for patent has been designed for attaching additional or insert sheets to the signatures or other sections Other objects and advantages of the in vention will appear in the detaileddescription hereinafter. j

In order that the invention may be better understood, reference had to the accompanying drawings, forming a part of this specification, and in said drawings:

Figure 1 is a plan vie-w of the machine; Fig. 2 is a side elevation thereof; Fig. Bis

an elevation viewed from the other side Fig. l is a cross-section onthe line 4+4 of Fig. 1; Fig. 5 is a longitudinal section on the line 55 of Fig. 1; Fig.6 is a sectional detail, largely diagrammatic. illustrating the paste applying operation, Fig. 7 is an enlarged sectional view on the line 77 of Fig. 1, and Fig. 8 is a similar View onthe line 8-8 of Fig. I j I Referring specifically to the drawings, the supporting frame of the machine comprises a pair of parallel and laterally spaced 1on gitudinal side rails 10 supportedby legs 11 which are connected by a suitable arrange ment of tie bars and braces, the side rails 10,

near one end of the machine carrying depending bearing brackets 12 supporting .a main drive shaft13 which obtains power from an electric motor 14 supported on a shelf 15 carried by the frame beneath the side rails. A belt drive 16 is shown, but an other driving connection between the motor 14 and the shaft 13 may be provided, and the" shaft may also obtain power from any other source. At the other end of the machine, the legs 11 carry bearings 17 which support a countershaft 18 obtaining motion from the main drive shaft 13, a chain or other suit able driving connection 19 being provided.

Each side rail 10 carriesan upstanding edge guide 20 for the Work, the same extending in the direction of the length of the ma-. chine... Between the guides 20 are positioned several rollers 21 having their axes parallel tosaid guides. Two sets of these rollers are provided, there being three rollers in each set. One set of rollers is adapted to be rotated in a direction to urge the work laterally toward oneguide 20, and the other set of rollers rotate inan opposite direction to urge theywork laterally toward the, other guide 20. The driving means for the rollers 21 comprise bevel gears 22 on one end there of andmeshing with bevel gears 23 on a transverse shaft 24 pr'ovidedwith apinion chains 29 to sprocket wheels 30 on a transverse shaft 31 at the otherend of the mav chine. Shaft 31' obtains motion from shaft 13. through a short shaft 32 having bevel gears 33 and 34 at its ends, one of which is in mesh with abevel gear 35 on shaft 13 and.

the other with a bevel gear 3 5 on shaft 31.

p The chains 29run parallel to the rollers 21, there being one chain for each set of rollers. "Between the chains and the rollers are filler strips 36 extending throughout the entire length of the machine. These strips form a work-supporting surface or table along which the work is fed by the chains 29, the latter being armed with fingers 37 which project above the table top to engage the work. The fingers may be in the form of rollers mounted on studscarried by the chain. The rollers 21 also project slightly above the top of the table so that they may come into contact with the under side of the work and carry the same laterally in the direct-ion of the edge guides 20.

Intermediate theends of the machine the I guides20 carry a pair of cross bars 88 which are. spaced in the direction of the length of the machine and support two pairs of shelves, the members of which are indicated at 39 and 40. i The members of the respective pairs of shelves arespaced at their inner longitudinal edges so that the fingers 37 of the chains 29 may extend into the spaces. One shelf 39 has its inner edge alongside one guide .20, and the other shelf 39 has its inner 7 justed laterally with respect to the shelves 39 according to the width of the work. The attachment is made by clamps 412 on the shelves a and carrying set screws 4H) for engaging'the cross bars. a

Inthe operation of the machine, paste is applied to the signature justbefore it passes under a pair of shelves 39 and 4:0, and the sheet to be attached is placed on said shelves. The finger 7 of the chain 29 which feeds the signature along beneath the shelves also feedszthe sheet as it. engages the rear edge thereof, and the sheet is now carried along with the signature but spaced therefrom vertically by the shelves' hen the signature issues from beneath thefshelves andthe sheet leaves the exit end of the latter, it drops down on thesignature and is carriedalong with the latter to a presser device compris ing two pairs of rollers 4% and4c5 bet ween which the signature and the superimposed sheet is fed. The rollers 44 press the sheet into intimate contact with the pasted portion of the signature, which'completes the operation, the finished work being discharged on a suitable holder to as it issues, from the presseii rollers.

The rollers 1 1 are on theshaft 31, and the rollers 45 are-ona shaft 47 obtaining motion from shaft 31 through a pinion 6L8 on one shaft meshing with a pinion L9 on the other shaft. V

The shaft {17 is supported by bracket arms 50 fastened to and extending laterally from a rock-sha t 51 supported in bearings 52on the side rails and provided with handles 53'. By operating the shaft 51, the shaft47 may be swung to carry the rollers away from and out of operativei'elation with re spect to the rollers 44. The'bracket arms are adjustably fastened to the rock shaft 51 by set screws 54:.

At 55 is shown a paste reservoir. It will be understood that the machine w illbe prov ded with two paste reservoirs, one for each unit. However as the construction and reservoir has a bottom outlet in which works a protrudingdistributing roller 56 carried by a transverse shaft 57 on one end of which is a pinion 58 which is in mesh with a pinion 59 loose on a shaft 60 parallel to the roller shaft 57. Pinion 59 is fastened to one side of a sprocket wheel 61 also loose on shaft 60v and connected by a drive chain 62 to a sprocket wheel 63 on the shaft 27.

The reservoir 55 is supported by the shaft 60, the attachment being made by a suitable bracket member 6d. The shaft 60 is adapted to be rocked for the purpose of tilting the reservoir 55 forwardly to lower the roller into contact with the signature along the edge to which the sheetis to be attached, this edge being along the guide 20. In order that this tilting movement of the reservoir may not disengage the pinions 58 and 59, the shaft 57 is supported by rocker arms 65 carried by the shaft 60, and hence said shaft swings with the reservoir when the latter is tilted. The following means are provided for tilting the reservoir The side rails 10 carry bearings 66 in which the shaft 60 is jo'urnaledp'and to one end of'the sha ft is connected a rocker arm 67 to which latter in turn is connected, inter mediate its ends, a pitman 68 obtaining motion from the counter-shaft 18. The inner end of the p'itma'n 68 is fitted with a fork G9 which slid ablv straddles the shaft 18, and on one side of the forkis mounted a roller 70. On the shaft 18 is fixeda cam or wiper 71 which, when the shaft is in motion, strikes the roller at every revolution of the shaft, whereby, through'qthe ,pitman- 68, the arm 67 is swung to rock the shaft 60 in one direction. To the outer endofthe arm 67 is connected one end of a rod 72 having its other end slidably supported by a suitable support 7 3 on one of the frame legs 11. Between the support 73 and an abutment 73 on the slide rod 72 is a spring .74, the same being coiled around the rod. When the cam 71, through the pitman 68, swings the arm 67 as hereinbefore described, the spring 74 is compressed as the rod '72 slides, and when the cam clears the roller 70, the spring expands and through the rod 72'. swings the arm 67 in an opposite direction, so that the sliaft60 is now again rocked, but in a direction opposite from that in which it was rocked. by the operation of the cam. as hereinbeforedescribed. Bythis operation the shaft 60, is rocked and the reservoir'55 carried therebyis tilted. j

On the shaft 18, alongside the cam 71 is loosely mounted a. second cam 75 adapted to be adjusted to form a continuation of the cam 71 for the purpose of timing the tilting of the reservoir 55. The cam 75 has an 'arcuate slot; '76 through which passes a stud '77 extending from one side of the cam and By shifting the cam 7 5"so:

the reservoir will occur earlier, and in this way an accurate adjustment may be made so that the reservoirremains tilted downwardly long enough to applypaste to one signature.

The operation of the machine may be summarized as follows: I

A stack of signatures "is supported on a shelf 79 extending from one side of the machine, and alongside said shelf is a second shelf 80 supporting a stack of the sheets which are to be pasted tothe signatures. If both units are to be operated, signature and sheet supporting shelves will be attached to the other side of the machine also. One operator is provided for each shelf for feeding the contents thereof tothe machine. The machine being in motion, a signature is placed on the forward end of the table or work supporting surface formed by the filler pieces 36 and a sheet is placed on one of the pairs of shelves 39 and 40. The signa ture is placed so that it will be worked over by the rollers 21 against theguideQO on the same side of the machine as the shelves on which the sheet was placed. Now when the rear edge of the signature is engaged by ci ated therewith.

one of'the projecting fingers 37 of the chain 29, the signature is pushed in the direction of the shelves and the paste reservoir asso- The signature is then pushed past the distributing roller 56 and a narrow strip of paste is applied, the paste reservoir having in the meantime been tilted to bring the roller in operative relation with respect to the signaturgand when the latter clears the roller the reservoir is tilted back to ele 'ate the roller. The signature next passes beneath the shelves 239 and i0 on which the sheet is lying, and when the chain finger which is propelling the signature reaches the rear edge of the sheet the sheet starts to travel along with the signature. When the sheet reaches the rear end of the shelves it drops down on the signature, and the latter and the sheet travel together in superimposed relation to the press-er rollers 41 i and 45. During the travel of the s gnature to the paste-applying apparatus it is continuously urged by the rollers 21 in "a lateral direction to keep one of its longitudinal edges in contact withthc guide 20, and the same action takes place when the signature and the superimposed sheet are traveling toward the presser rollers 44 and 415. guided that the sheet is accurately pasted to the signature. It will be noted that the sheet-exit end of the shelf '39 terminates short of the corresponding end of the shelf 40, with the result that the portion of the sheetwhich is to be pasted to the signature first drops down to catch the coat-ed portion of the signature. While traveling along the By this operation the two parts are so shelves 39 and 40, the sheet is guided by the guide 20 and the flange 41. i

The connection loetween the arm 67 and the rock shaft 60 is an adjustable one, As shown in Figures .7 and 8 the shaft .60 passes loosely through a hub 67*on the arm 67, and on the endof the shaft is fastened a crank memberSO having at its outerend a laterally extending portion '81 which over-f hangs theshaft and has a slot or recess 82 extending transversely of the shaft. The

upper end of the arm 67 extends into the recess 82 and is here engaged on opposite sides by adjusting screws 83 threaded through the sides of the part 81. By means of these screws, the shaft 60 carrying'the reservoir 55 may be rocked to tilt the reservoir, and in this manner the paste-applying roller 56 is adjusted accordingto the thickness of the signatures, the reservoir being tilted back when the machine is to operate on signatures containing a largenumber of sheets, andtiltedforwardly when the signatures contain fewer sheets. The pasteapplying n'i-echanism cantherefore be 'acCurately adjusted to signatures varying ,in thickness. v M

The operation of the cam mechanism which actuates the ar1n67 is so timed that the reservoir 55 tilts to bring the roller 56 to paste-applying position shortly after the forward edge of the signature has passed the roller, and the reservoir is tilted back to remove the roller from the signature before the rear end of the signature reaches the roller. In this manner paste is not, applied to thesignatures adjacent to. the ends thereof, which is desirable for the reason that if the paste extended throughout the entire length ofthe signature. it would be squeezed out at the ends when the insert sheet is pressed on hythe rollers l-tand 4:5. The adjustment of the cam mechanism herc{ inbefore described enables the lengthof the working strokes of the roller 56t0 be varied according to the length of the signatures. In order to hold down the signature as it passes to the paste-applier, especially if its forward edge has atendency to curlu'pwardly, there is mounted close to the roller 56 a flexible guard plate 8a, beneath which the signature passes, said plate being carried by across bar 85 supported'by'the guides 20.
